United States PatentO 3,501,821 TOOLHOLDER Harry E. Ford, 4627 Caroline Ave. NE, Salem, Oreg. 97303 Filed Sept. 30, 1968, Ser. No. 763,628 Int. Cl. B23d 71/04 US. CI. 29-80 1 Claim ABSTRACT OF THE DISCLOSURE A toolholder especially adapted for use with flat files and similar hand tools. The main body of the holder is of substantially tubular form with two depending normally parallel flanges adapted to be compressed and/or deformed into secure gripping engagement with a file, or the like, firmly secured between the flanges for filing operations.

The objects of the invention are:

To provide a toolholder as above described which is of simple, eflicient, durable construction, made of sheet metal by simple stamping and bending jigs.

To provide a holder of the character described which is readily adjustable into secure holding engagement with the sides of files of various thicknesses and of any standard length.

To provide a holder of the character described which is particularly well adapted, though not restrictively, for filing the right angular working edges of such tools as masonry trowels and the like which are dulled by their scraping contact with work being dealt with.

The foregoing and other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof and in which:

FIGURE 1 is a top plan view of a tool holder made in accordance with my invention.

FIGURE 2 is a side elevational view of FIGURE 1.

FIGURE 3 is a bottom plan view of FIGURE 2.

FIGURE 4 is a view on an enlarged scale, of the left end of FIGURE 3, showing the bending or conforming and gripping characteristics of the flanges of the holder, and

FIGURE 5 is a View similar to FIGURE 4 with the file removed and the flanges of the holder in parallel relation throughout their length.

With continuing reference to the drawing wherein like reference numerals designate like parts, numeral 1 indicates generally the main body of the device which is of substantially hollow tubular form throughout its length with its ends rounded as at 2 and 3.

As best illustrated in FIGURE 5, the body 1 is divided to provide flanges 4 and 5 which when in an inoperative position extend downwardly in parallel relation to each other and are internally shouldered as at 6 and 7 to support a file or similar tool indicated at 8 in FIGURE 4.

The flanges 4 and 5 are provided with opposing screw fasteners 9 and 10 extending inwardly into threaded engagement with an through a longitudinal bar 12 which extends substantially throughout the length of the holder, and as best illustrated in FIGURE 3 the screw fasteners are offset relative to each other.

From the foregoing it will be readily understood that advancing all of the screws on their threads to a predetermined extent will pull the flanges 4 and 5 toward each other in parallel relation throughout their length. It will also be understood that advancing the screws at either end of the device, such as those at the left end of FIGURE 3 but to a greater extent than the others will draw that end portion of the holder into conformity with the tapering end portion of a file while the central screws and those to the right, although advanced to a lesser extent, will securely grip the parallel sides of the file.

It will also be apparent that a file gripped between the flanges 4 and 5 will be fully operational throughout its length on a horizontal plane because of the length of the main body of the device within the grip of both hands of an operator, and that either flange will serve as a guide in filling a workpiece at right angles to the file.

What is claimed is: g

1. A toolholder comprising an elongated body member having two spaced apart normally parallel flanges depending therefrom,

a bar disposed between and extending lengthwise of said flanges, said bar having threaded openings therethrough, said flanges having openings therethrough aligned with said threaded openings in said bar,

screw fasteners extending through said openings in the flanges and through said threaded openings in the bar,

whereby equal advancement of said screw fasteners through said bar will deflect said flanges uniformly toward Or away from each other in parallel relation, and whereby advancing certain of said screw fasteners independently of the others will deflect said flanges into non-parallel relation to thereby grip a too] having non-parallel side edges.
